Specifically, in an exemplary embodiment, the spread 408 is maintained in both the fore-aft direction and the cross vehicle direction, by installing the different bolts 404, 406 in different directions at a given line of axis of the shock cap assembly 102 that are at least a predetermined angular difference from one another. In various embodiments, the spread 408 and bolt orientation allow sufficient tool access.

FIG. 5 is a flowchart of a process 500 for installing a shock cap assembly 102 in a vehicle 100, in accordance with an exemplary embodiment. In an exemplary embodiment, the process 500 can be implemented in connection with the vehicle 100 of FIG. 1 and the shock cap assembly 102 of FIGS. 2-4.

As depicted in FIG. 5, the process 500 begins at 502. In certain embodiments, the process 500 begins as manufacturing begins for a particular vehicle 100.

In various embodiments, at 504, a strut component is assembled to a cap component, to produce the shock cap assembly 102 of FIGS. 1-4. With reference to FIG. 6, the shock cap assembly 102 is depicted with the strut component 602 attached to the cap component 604 following step 504.

With reference back to FIG. 5, also in various embodiment, separately, at 506, the body 110 of the vehicle 100 of FIG. 1 is assembled, separate from the shock cap assembly 102. With reference to FIG. 7, the body 110 of the vehicle 100 is shown as assembled following step 506, with the front vehicle structure but without the shock cap assembly 102. It will be appreciated that in various embodiments steps 504 and 506 may be performed in either order or simultaneously with one another in various embodiments. In addition, at 508 (or at 512, further below), various other components of the vehicle 100 may also be assembled, such as, by way of example, painting of the vehicle 100.

With further reference to FIG. 5, at 510 the shock cap assembly 102 is installed into the vehicle 100. For example, in various embodiments, during step 510, the shock cap assembly 102 of FIG. 7 is installed into the vehicle body 110 of FIG. 6, thereby resulting in the installed shock cap assembly 102 as installed into the vehicle 100 and depicted in FIGS. 2-4 and described above in connection therewith.

In various embodiments, during step 510, the installing of the shock cap assembly 102 into the body 110 of the vehicle is performed via access through a front wheel well of the vehicle (e.g., wheel well 111 of FIG. 1). Also in various embodiments, during step 510, the installing of the shock cap assembly 102 into the body 110 of the vehicle 100 comprises bolting the shock cap assembly 102 to the body 110 of the vehicle 100 via a first plurality of substantially horizontal bolts and a second plurality of substantially vertical bolts that maintain a spread in both a fore-aft direction and a cross vehicle direction in different directions at a given line of axis of the shock cap assembly that are at least a predetermined angular difference from one another (for example, as depicted in FIG. 4 and described above in connection therewith). In addition, also in an exemplary embodiment, the installing of the shock cap assembly 102 into the body 110 of the vehicle 100 during step 510 further comprises installing the shock cap assembly 102 into the body 110 of the vehicle underneath a front windshield 104 of the vehicle 100 that is disposed forward of a front axle 114 of the vehicle, as depicted in FIGS. 1 and 2 and described above in connection therewith.

In various embodiments, following step 510, other components are assembled (e.g., installation of suspension control arms, wheels, and tires) at 512. Also in various embodiments, the process 500 thereafter ends at 514, when the manufacturing of the vehicle 100 is complete.

As described in greater detail further below in connection with FIGS. 8-11, the process 500 results in a shock cap assembly 102 that is accessible via the wheel well 111 of the vehicle 100, and that also provides integral structural support for the windshield 104 via a torsional hoop structure, as well as contributing to overall body rigidity and managing the loads from the shocks.

FIGS. 8-9 provide perspective diagrams of a torsional hoop structure for a front portion of a vehicle (such as the vehicle 100 of FIG. 1), before and after the installation of the shock cap assembly 102 into the vehicle 100 during step 510 of FIG. 8.

Specifically, FIG. 8 is a front view of the torsional hoop structure 801 for a front portion of the vehicle 100, prior to installation of the shock cap assembly 102 of step 510, in accordance with an exemplary embodiment. In addition, FIG. 9 is a front view of the torsional hoop structure 801 for the front portion of the vehicle 100, after installation of the shock cap assembly 102 during step 510, also in accordance with an exemplary embodiment.

As shown in FIGS. 8-9, the torsional hoop structure 801 includes a windshield base structure 802 (e.g., corresponding to base of windshield support structure 202 of FIG. 2), a chassis 804, a longitudinal rail 808 (depicted in accordance with an end view in FIGS. 8 and 9), a front compartment rail 810 (e.g., which may be a casting in certain embodiments, and/or which may take another form, such as stampings, in other embodiments), and shock tower brackets 812 that connect the window base structure 802 with the shock caps 930 along with an integrated beam (e.g., corresponding to the integrated brace 204 of FIGS. 2 and 4 and the integrated brace 100 of FIGS. 10 and 11).

As shown in FIG. 8, the torsional hoop structure 801 comprises an incomplete loop 820 prior to the installation of the shock cap assembly 102 of step 510, due to a relatively weak connection in the upper corners. Conversely, as shown in FIG. 9, following the installation of the shock cap assembly 102 of step 510, respective shock caps 930 as shown in FIG. 9 are installed, closing the torsional loop structure with a completed loop 940, by creating a stiff, strong connection of the corners, precisely at the point of high loading.

In various embodiments, the torsional hoop structure 940 is formed by the integrated cross car beam (which is part of the windshield base structure) at the top, the chassis at the bottom, and the front compartment rails on the sides. Also in various embodiments, the shock cap assembly joins vertical members (namely, front compartment rails) to the upper horizontal member (namely, the integrated cross beam).

Also as depicted in FIGS. 8 and 9, in certain embodiments mid beam 806 may also be included, for example as a secondary member for various purposes, such as attachment of other components, as well as providing some structural support to the vehicle 100.

Further, with reference to FIGS. 10-11, the support structure for the shock cap assembly 102 as installed in the vehicle 100 is depicted with greater detail, and is described below in connection therewith. Specifically, (i) FIG. 10 is a front perspective view, and (ii) FIG. 11 is a top perspective view, both of the front portion of the vehicle, with the shock cap system 102 installed, in accordance with the process 500 of FIG. 5, the vehicle 100 of FIG. 1, and the shock cap assembly 102 and components from FIGS. 1-4, and 6-9, in accordance with an exemplary embodiment.

As depicted in FIGS. 10 and 11, the shock cap assembly 102 provides an integrated brace for the vehicle 100, as the shock cap assembly 102 is installed into the windshield base structure 802. Specifically, in various embodiments, as the shock cap assembly 102 is installed underneath the windshield 104, combined with the shock tower brackets 812 (from FIGS. 8 and 9) provides cross-vehicle support for the windshield 104, in the form of an integrated brace 1000 for the windshield 104 (e.g., as the integrated brace 1000 is integrated into the windshield base structure 802). In various embodiments, the integrated brace 1000 (which may correspond in various embodiments to the integrated brace 204 of FIGS. 2 and 4) is generated from the position of the shock cap assembly 102 under the windshield 104 and the integration into the windshield base structure 802, along with the shock tower brackets 1002. Also in various embodiments, this configuration provides for a dual-purpose, integrated cross vehicle brace with the windshield support structure 802, to provide structural continuity for the windshield 104 and between the shock tower brackets 812, in an exemplary embodiment. In addition, also in an exemplary embodiment, the high location of the integrated brace 1000 also potentially improves packaging for other components of the vehicle such as, by way of example, an HVAC system for the vehicle 100.

In various embodiments, the support structure provided by the integrated brace 1000 of this configuration provides additional structural support for the windshield 104, which may be needed as a result of the windshield being cantilevered due to its placement forward of the front axle 114 of the vehicle 100. In addition, this configuration with the integrated brace 1000 (including the hoop structure with the cross-support shock tower brackets 812) further provides structural continuity between the shock cap assembly 102 and the windshield base structure 802, without requiring redundant structure for cross-support. In short, in an exemplary embodiment, integral support is provided as the shock cap assembly 102 provides structural support for the windshield 104 (e.g., via the brackets 812 of FIGS. 8 and 9), and the windshield base structure 802 in turn provides structural support for the shock cap assembly 102.

In various embodiments, the torsional hoop structure is formed by the integrated cross car beam 1000 (which is part of the windshield base structure) at the top, the chassis 804 at the bottom, and the front compartment rails 810 on the sides. Also in various embodiments, in so doing, the shock cap assembly 102 joins vertical members (namely, front compartment rails 810) to the upper horizontal member (namely, the integrated cross beam 1000). In various embodiments, the torsional hoop structure not only provides structural support for the windshield 104, but also contributes to the overall body rigidity for the vehicle 100 and manages loads from the shocks.

In addition, as noted above, in certain embodiments mid beam 806 may also be included, for example as a secondary member for various purposes, such as attachment of other components, as well as providing some structural support to the vehicle 100.

Accordingly, systems, methods, and vehicle are provided for shock cap assemblies installed in vehicles. In various embodiments, the shock cap assemblies are sub-assembled prior to installation in the vehicle. Also in various embodiments, the configuration of the shock cap assemblies as installed in the vehicle enables the shock cap assembly to be accessed from the side of the vehicle, via a vehicle wheel well, for installation, service, repair, and removal. This is particularly useful for, but is not limited to, configurations in which the windshield covers the shock towers from above, and/or in which a vehicle floor, occupant compartment, and/or other vehicle components may preclude access from above.

In addition, in various embodiments, the installed shock cap assembly includes an integrated beam connected to the shock tower to complete a torsional hoop structure that results in an integrated support system for the shock cap assembly and the windshield support structure, by which the windshield base structure and shock cap assembly mutually support one another in an integrated manner. In addition, in various embodiments, the installation of the shock cap assembly in the vehicle utilized with an integrated cross-vehicle brace in the windshield support structure provides structural continuity without the need for a separate structure element, such as a separate tower-to-tower brace. In various embodiments, the torsional hoop structure also contributes to overall body rigidity and managing loads from shocks of the vehicle 100.

It will be appreciated that the systems, vehicles, methods, applications, and implementations may vary from those depicted in the Figures and described herein. For example, in various embodiments, the vehicle 100, the shock cap assembly 102, the windshield 104, and/or various components thereof, and/or other components may differ from those depicted in FIGS. 1-11 and/or described above in connection therewith. It will also be appreciated that the steps of the process 500 may differ, and/or that various steps thereof may be performed simultaneously and/or in a different order, than those depicted in FIG. 5 and/or described above.

While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the disclosure in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing the exemplary embodiment or exemplary embodiments. It should be understood that various changes can be made in the function and arrangement of elements without departing from the scope of the disclosure as set forth in the appended claims and the legal equivalents thereof
